Hi well to do this you need a service manual, these have exploded diagrams and circuits and schematics too, for your exact make and model, these can usually be obtained via the 'net or through a direct approach to the manufacturer or agent. I have had a search for one but have been unable to find any for free but there is a buy link below too ...? Also accordingly i give you a link, so you can contact the manufacturers agent, to hopefully obtain one?

This is most likely caused by a damaged or misaligned video drum and can usually be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired by a qualified service technician.
